Sababtoo ah sifooyinka fiilooyinka dhoobada dhoobada, waxaa loo isticmaalaa in lagu beddelo foornada warshadaha, sidaas darteed kaydinta kulaylka ee foornada lafteeda iyo kulaylka luminta iyada oo loo marayo jidhka foornada ayaa si weyn loo dhimay. Sidaa darteed, heerka isticmaalka tamarta kulaylka foornada ayaa si weyn loo hagaajiyay. Waxay sidoo kale wanaajisaa awoodda kuleylka iyo waxtarka wax soo saarka ee foornada. Dhanka kale, wakhtiga kuleylka ee foornada waa la gaabiyaa, oksaydhka iyo decarburization of workpiece waa la dhimay, tayada kuleylka ayaa la wanaajiyey. Ka dib markii dahaarka dhoobada dhoobada ah lagu dhejiyo foornada daaweynta kuleylka gaaska, saameynta tamarta tamarta ayaa gaareysa 30-50%, waxtarka wax soo saarka ayaa kordhay 18-35%.
Sababo la xiriira isticmaalkadaboolka dhoobada dhoobadasida foornada foornada, kuleylka kuleylka ee derbiga foornada ee dibadda ayaa si weyn hoos ugu dhacay. Celceliska heerkulka foornada dusha derbiga dibadda ayaa laga dhimay 115 ° C ilaa 50 ° C. Gubashada iyo shucaaca kulaylka kuleyliyaha gudaha foornada ayaa la xoojiyaa, heerka kuleylka ayaa la dardargeliyay, sidaas awgeed waxtarka kuleylka ee foornada ayaa la wanaajiyaa, isticmaalka tamarta foornada ayaa la yareeyaa, wax soo saarka foornada ayaa la wanaajiyaa. Intaa waxaa dheer, xaaladaha wax soo saarka ee isku midka ah iyo xaaladaha kulaylka, derbiga foornada ayaa laga dhigi karaa mid aad u khafiif ah, taas oo yaraynaysa miisaanka foornada, taas oo ku habboon hagaajinta iyo dayactirka.
